Should i do water changes when cycling an aquaponics system?

Question by Marvin: Should i do water changes when cycling an aquaponics system?
I have just set up an aquaponics system. It is a 10 gallon tank stocked with 2 goldfish and a pump that drains into 10 pounds of gravel, which then drip drains back into the tanks. Everywhere that I look that describes cycling of a standard fish tank says to do 20% water changes weekly. Is it the same for an aquaponics system prior to planting in the growbed, or should I just let all of the nitrites build up in the system and then plant?

What do you think? Answer below!
